How is that the MAC address (BIA : Burn -in -Address) not yet exhausted?

How is that the MAC address (BIA : Burn -in -Address) not yet exhausted? IPV4 is exhausted and we are moving to IPV6!

MAC addresses are 48 bits long. That is 65536 times the IPv4 space. IP addresses need to be globally unique while MAC addresses only need to be unique on their local LAN segment (LAN/VLAN).
Here is a good link explaining it more in detail:

There is also a link there that suggests some edits to the 24-bit OUI assignments:

    Hi Bruce,
    Out from what I can find on this network card is it not possible to get the mac address without a OS. I would recommend you to get/burn a Linux/Ubuntu live CD/DVD and run a Ifconfig in there.
    Hope it helps you.

  • How to change the mac address of thunderbolt to ethernet adapter?

    Hello everyone,
    I am using Macbook pro retina display 2013 version. I have bought a thunderbolt to ethernet adapter in order to connect my Macbook to LAN. But in my area there is a shared line and I have to clone their mac address to my Macbolok. I could not change the mac address of my thunderbot to ethernet adapter. Can anyone please tell me how to change the mac address of thunderbot to ethernet adapter step by step??
    Thanks in advance.

    Open terminal and type the followings;
    1) sudo ifconfig bridge0  ether xx:xx:xx:xx:xx:xx(it will be your new mac address)
    2) Type your password to confirm
    3) ifconfig bridge0 |grep ether (to see if change is successful)
    PS: *This should with your thunderbolt adapter, but its not working usb to ethernet adapters without installing required drivers.
           ** You may need to do these steps every time you boot your mac.

  • How to get the MAC address of a PXI in a dll

    Hi,
    I am looking for a way to get the MAC address of a PXI RT controller. I know that there is a VI to do this, but I am looking for a solution for a dll (C-Code).
    I use the "Call library node" to call this dll and want to make sure that it is only used on a specific PXI.
    Since the VI provides the functionality, I am wondering if it is also available to be called from C-Code?
    Thank you,

    If it is available in LabVIEW it is probably available in CVI, which you could then build into a DLL (if there isn't one available already).

    If you need to setup wifi to start the MAC address with iPad, try  the http://www.ipad-tablet-help.com/2010/03/how-to-find-ipad-mac-address.html   to find it out.  Works for iOS5.

  • How to find the mac address

    I am trying to connect my iPad to my Netgear router and activate the user list. Amazingly the router status does not show the iPad although it is connected. I used the mac address which I found under settings --> general --> info. I used the WLAN address to add it to the routers user list. Unfortunately it did not work. Any idea which other address I could use and where to find it on the iPad. Thanks for the help.

    Does it show under Options | Status as a WLAN Mac Address?

  • Bought iPod on the apple store but the wrong address not yet dispatched

    Hi,
    I bought an iPod on the apple store online and checked everything before submitting the order. However when I got the conformation email the delivery address is not what was set. Now apple have all their offices closed today (typical), is there any way of contacting apple in regards to this matter as I do not want the order to be processed as if it does then there is nothing they can do IIRC.

    I think your goal is to speak to a person. So I would call 1-800-myapple and select the option to get a sales person, not a service person. +Service for an existing order+ may be closed on the weekend, but I can't believe they would be closed over the weekend for a +new sale+. That would be like closing the local physical Apple Store on weekends.

  • How to change the already synced voice memo status to not yet sync

    When syncing my iPhone with my computer, some random error occurred and thus the syncing process was not completed and it was forced to stop. Due to this reason, i have 5 voice memos were not transferred into my computer but all of the voice memos were marked with today's date under the 'Date Added" column. In fact, they were all not transferred into my computer. Any advice or solution for this kind of problem?

    On windows XP or linux have a MAC adress Change function  allow 00 mac adress and another normal mac adress range.On windows 8.1 all Mac changer program dont work.This 2,6,A,E on second adress are not vaild Mac adress. You simply can not use normal MAC
    addresses on windows 8.1.When i connect the usb the Pc windows 8.1 recognizes the adapter but the default  driver and the downloaded ralink driver the same problem.On windows xp the current driver works perfectly have (Local Mac Network Adress) funktion
    and works with the 802.11b hot spot.I got the internet my PC and laptop too public HotSpots and another wifi HotSpots if wont work correctly i can not use neither the windows 7,8,8.1 or 10. Many users have expressed interest in the problem more forums.
    The 3. problem im tested in virtualbox the windows 7 and 8.1 on 8.1 (on the blue wifi platform) not show correctly the signal strengh. On windows 7 show this correctly.The windows 7-8.1 Configure/advanced the advanced options on Ralink 3070 the default (windows
    driver) somehow downgraded function is less than for Xp. Configure/advanced the advanced options (needs to be upgraded in the future) because it does not advance but rather regressed.
    Today it is very common these wi-fi technology increasingly used (hotels,Public Hots Spots,Internet coffe,) growing free bublic wifi projects. The wifi funktions on windows  need debugging and modernize.The quality of Wi-Fi is now the operating system
    is now a thing order which is not good then the operating system is unusable.

    Hi,
    For changing the MAC address for Windows 7 is designed with some limitation, we cannot get over it. Thanks for your understanding.
    Under Windows 7, the possible range of spoofed addresses for wireless adapters that can be set is limited.  To be used by Windows 7, a spoofed MAC address should have 0 as a least significant bit (unicast) and 1 as a second least significant
    bit (locally administered) in the second nibble.  Thus possible values for the second nibble are limited to 2, 6, A and E.
    In other words 
    MAC address:  “XY-XX-XX-XX-XX-XX” “X” can be anything hexadecimal.  The hexadecimal “Y”, written in binary format, is  Y:  “kmnp”,  where “p” is the least significant bit; 
    p=0 --> unicast;
    p=1 --> multicast;
    n=0 --> globally assigned MAC;
    n=1 --> locally administered;
    So, actually MAC can be changed  to any combination in which p=0 and n=1;
    “Y” can be 2, 6, A or E.
    So the possible MAC addresses in Windows 7 for wireless adapters:
    X2-XX-XX-XX-XX-XX
    X6-XX-XX-XX-XX-XX
    XA-XX-XX-XX-XX-XX
    XE-XX-XX-XX-XX-XX

    sudo ifconfig en0 lladdr 00:00:00:00:00:00
    but i remember trying it without success, anyone has a clue how to change the MAC address in leopard? on top of it - why on earth would they downgrade a system? is this one of these 300 new features? sweet :P
